For those who don't speak a lot using mobile (like me), but still interested in 4G + SMS there is an offer to look at: Orange by digitec

You get 1GB + unlimited calls inside orange + unlimited SMS + s5 or s5 mini for free which is not locked and you can sell it immediately if you don't need one + 60 mins in all other networks if you pick s5. Price 35/20 CHF/month depending which phone you have chosen + 40 CHF for the sim-card.

I managed to test call diverts with das-abo, and the result is the best possible:

It is possible to divert calls to all numbers, also abroad, and it's not charged separately! A divert is charged and listed as if you effected a normal call to this number. So when included in the flat rate this is equally included.

What this means:
When roaming, instead of using the roaming-rates offered by das-abo, you just divert your number to a local number of where you happen to be. As such, receiving calls on your Swiss number is suddenly FREE (as opposed to das-abo roaming rates).

How to combine this:

You can get local SIM-cards of wherever you are and divert your Swiss number directly to those. This way you can receive calls on your Swiss number, free of charge, without giving anyone a different number. No one would even notice or know.

A German www.alditalk.de prepaid card would provide this option for all of the EU, since they have free incoming throughout the EU. So when out-of-Switzerland you divert "all calls" to your German Aldi-number, and never have to worry about getting too many cards. Remaining problem: Data. While Aldi does offer one data-package for the rest of the EU, it's not great (€4.99 for 150MB valid for 7 days). However, if this suffices, this might be the best and easiest option.

all calls from you Swiss das-abo number are now diverted to your German number. This is included in das-abo's flat fee and hence doesn't cost anything

when someone calls your Swiss number, your German number will ring instead, throughout the EU free of charge (as explained above)

when back to Switzerland, just enter ##21# - the divert is cancelled and all calls go directly to your Swiss phone as before

if you're not sure what the story is, enter *#21#, and the phone will display your current divert status

It´s not complicated at all to get used to this, and it can and will save you a lot!

PS - there are a lot more divert-strategies, both automating things and also for other countries such as South-East-Asia where no flatrates apply. But I won't dig into them if no-one even uses the simplest version as per above.

Love it!

Unfortunately I'm tied to my contract for another 12 months so can't change until then.

Was thinking of getting this but think the data plan is a joke, 500mb a month, are they still living the times before smartphones. It should be at least 5gigs for normal user or unlimited if one uses spotify or similar.
